Airbag and method of production of airbag

A method of production of an airbag which is inflatable with an inflation gas by separating a pair of opposing walls,

• wherein the airbag includes a joint region of outer circumferential edges of the pair of walls;
• wherein the joint region includes, between the outer circumferential edges of the pair of walls, a sealing member which has elasticity, and has adhesiveness in an unsolidified state;
• wherein the joint region is formed by such a sewing that runs a sewing thread through an application area of the sealing member;
• wherein the sealing member is formed into a line a width of which is greater than that of the sewing thread;
• and
• wherein the joint region includes a region in which the sealing member has a solidified, thus non-adhesive surface, and is pressed against at least one of the pair of walls by the non-adhesive surface, and penetrated by the sewing thread in that state, the method of production comprising:
• applying a sealing agent to the other of the pair of walls and solidifying the sealing agent so as to form the sealing member provided with the non-adhesive surface, and forming the joint region in which the non-adhesive surface of the sealing member is pressed against the one of the pair of walls, by sewing the outer circumferential edges of the pair of walls together by running the sewing thread through the application area of the sealing member in a state that the non-adhesive surface of the sealing member is pressed against the one of the pair of walls.

• and
• wherein the sealing member is composed of a sealing agent that has been applied to a flexible base member that corresponds in contour to the joint region of the outer circumferential edges of the pair of walls, then solidified, such that the sealing member is provided with the non-adhesive surface,
• the method of production comprising:
• placing the sealing member between the pair of walls;
• and
• forming the joint region in which the non-adhesive surface of the sealing member is pressed against the one of the pair of walls by pressing the non-adhesive surface of the sealing member against the one of the pair of walls and sewing the outer circumferential edges of the pair of walls together by running the sewing thread through the application area of the sealing member.
